Description
Technical field
The utility model belongs to liquid-level switch technical field, specifically a kind of adjustable safety liquid-level switch.
Background technique
In the prior art, float type level switch is more common, and industrial common structure is the hollow cylinder in sealing
Built-in magnetic reed switch, then in hollow cylinder housing floating ball, floating ball is equipped with magnet, with floating ball up and down, magnet influences magnetic red and opens
The movement of pass.After long-term use, impurity in liquid etc. can be adhered to outside hollow cylinder and floating ball, caused hollow cylinder and floated
Relative motion clamping stagnation between ball, is unable to learn in time liquid level, can not also know the case where device failure in some hollow cylinders
Liquid level causes liquid level excessively high.Currently, solving the problems, such as this, usually the output signal of liquid-level switch is monitored, to exception
State carries out automatic or manual identification, when necessary, site inspection, maintenance replacement.Which is more time-consuming, has identification careless omission can
It can property.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of adjustable safety liquid levels to open
It closes, including hollow pipeline and covers the first floating ball outside hollow pipeline；It is opened along the vertical direction equipped with multiple magnetic reds in hollow pipeline
It closes, first floating ball is equipped with magnet corresponding with each magnetic reed switch, it is characterized in that further including alarm device；Alarm device packet
Include the trigger mechanism of microswitch, the second floating ball and microswitch；The contact extraction wire of the microswitch (is accused for issuing
Alert information)；The microswitch is connected to the top of hollow pipeline outer wall；
The trigger mechanism of microswitch includes conduit, first piston, second piston and the second floating ball；The conduit is
" L " type；Conduit is connected to outside hollow pipeline by bracket；Height where the height of conduit horizontal segment and the button of microswitch is right
It answers, and the open end of conduit horizontal segment is towards the button of microswitch, and first piston is connected in open end, first piston connects
Contact bar；Pressure spring is connected between first piston and hollow pipeline outer wall；Conduit vertical section it is opening down, in conduit vertical section
Open end in connect second piston, second floating ball by connecting rod be connected to second piston lower section；Filled with liquid in conduit
Medium；Branch pipe is connected on conduit, branch pipe is connected to conduit；It is provided with internal screw thread in the open end of branch pipe, a plug passes through spiral shell
Rotation connection structure is connected in the open end of branch pipe.
The principles of the present invention are, when liquid level rising reaches warning liquid level, and the sliding of the first floating ball is unsmooth, by the
Two floating balls float the button of pressing microswitch, and then alerted by the external circuit for microswitch contact of ining succession outside (such as
The switching value that microswitch is inputted as PLC).Since liquid medium is influenced by temperature etc., effective row of feeler lever will affect
Journey.And it can solve this problem by the advance and retreat of the plug on branch pipe to finely tune the total volume of liquid medium.
In Project Realization, two open ends of conduit can install the blind plate with through-hole, for preventing piston from surprisingly sliding
Conduit (under normality, can ensure that two pistons do not skid off conduit by the pressure difference at piston both ends) out.Through-hole on blind plate is for connecting
The rod-like structure connect on piston passes through.
Further, the pressing plate of outer convex is connected on the feeler lever.The structure ensures reliably to press microswitch
Button.
Further, the length of connecting rod between second floating ball and second piston is adjustable.Length of connecting rod can transfer to be applicable in not
It warns and requires with height level.
The utility model is suitable for the warning of a variety of liquid levels.
Detailed description of the invention
Fig. 1 is the structure principle chart of the utility model；
Fig. 2 is the principle schematic diagram of the trigger mechanism of microswitch；
In figure: hollow pipeline 1, the first floating ball 2, magnetic reed switch 3, magnet 4, microswitch 5, the second floating ball 6, connecting rod 7, pressure
